I'm a sucker for mysterious doors out in the woods. This building is stone all the way around, no windows or other doors. The sign over the door says 1913. No door knob, but it has a modern lock.
I'm sure I would be disappointed by whatever is actually in there, the unknown is usually more interesting than the known. My best guess is that it's related to some old radio towers near by, since it's on the top of a mountain, but those towers are long dis-used, and there's that modern lock...
